A camp has provision for 9 days for 500 men. At the end of 3 days 100 more men were admitted. How long will the food now last?
Correct answer: B. 5 days
- A. 12 days
- B. 5 days
- C. 9 days
- D. 6 days
Explanation
The original stock equals 500 men x 9 days = 4500 man-days. The first 3 days use 500 x 3 = 1500 man-days, leaving 3000 man-days; with 600 men, it lasts 3000 ÷ 600 = 5 days. The likely mistake is 9 days, found by ignoring the 100 additional men.
